Kernel 2.4: HZ = 1000, kernel panic

I have RedHat 9.0, kernel 2.4.20-31.9. I need more than 10 ms precision.
I have changed HZ from 100 to 1000 in
'/usr/src/linux-2.4/include/asm-i386/param.h':

#define HZ 1000

I have rebuild the kernel, but now when booting the new kernel I get a
kernel panic, something like this:

Process swapper
...
Kernel panic: Aiee, killing interrupt handler!
In interrupt handler - not syncing

What's the problem?
Do I need to change something else too? Only to change the HZ value is not
enough?

Thank you.
